LEWISTON, Maine (AP) — The father of a 13-year-old boy who drowned on a field trip to a Maine state park is suing the state and the city of Lewiston in federal court.

The Sun Journal newspaper reports that the lawsuit filed by Ali Abdisamad seeks unspecified damages for medical costs and funeral expenses, along with pain and suffering.

His son, Rayan Isa, was a seventh-grader at Lewiston Middle School when he drowned during a field trip to Range Pond State Park on June 12, 2018.

Eleven school employees were chaperones and one lifeguard was on duty with 111 students. Officials said Isa was within a buoyed area when he ended up in water that was 8 to 10 feet deep.

A state agency and city school superintendent didn't immediately return calls seeking comment Friday.
